AIR-BRAKE DETAIL.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed April 26, 1913. Serial No. 763,913.

T 0 all whom it may concern:

Be it known that I, BENJAMIN'W. DAVIS, a citizen of the United States,residing at Evanston, in the county of Uinta and State of lVyoming, haveinvented a new and useful Air-Brake Detail, of which the following is a.specification.

The device forming the subject matter of this application, is adapted tobe employed for manipulating the angle cocks in the train pipe line ofan air brake system.

This invention aims to provide a means for controlling the angle cock ofa train pipe line in an air brake system, which means may readily beassembled with an angle cock of standard construction, without makingchanges in the angle cock.

The invention aims further, to provide a device of the type describedwhich will not be subject to injury when the draw bar is extracted, orwhen the car is chained up.

Another object of the invention is to provide a means for controllingthe angle cock, which means will be within full view of the operator,and be entirely accessible for repair.

I The invention aims, as another object, to provide, as an article ofmanufacture, an angle cock cont-rolling means, one element of which atthe will of the operator, may be omitted, so as to vary the height atwhich the operating handles are located with respect to the angle cock.

It is within the scope of the invention to improve generally and enhancethe utility of, devices of that type to which the present inventionappertains. I

Vith the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combina-' tion andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawing :Figure 1 shows in top plan, a car to which the deviceforming the subject matter of the present invention has been applied;Fig. 2 is a side elevation of the structure shown in Fig. 1; Fig. 3 isan end elevation of the sill of the car, showing a portion of thepresent invention assembled therewith; Fig. 4 is a side elevation of thestandard; Fig. 5 is a bottom plan of the standard; Fig. 6 is a plan ofthe lever which is assembled with the standard; Fig. 7 I

is a side elevation of one of the slide bearings through which theoperating handles move; Figs. 8 and 9 are sectional details of the anglecock, the valve thereof being disposed in different positions, and F ig.10 is a side elevation showing the lever applied directly to the valve.I

In the drawings there is shown a car 1 provided with an end sill 2 andwith a draw bar 3, the train pipe being denoted by the numeral 4 and thecoupling hose by the numeral 5. The angle cock mechanism connects thetrain pipe 4 with the coupling hose 5 and preferably is of standardconstruction. The angle cock, however, may include a casing 6 providedat one side with a bleed port 7. J ournaled in the casing 6 is a valve8, provided at its upper end with the usual polygonal lug 8 indicated inFig. 2. The valve 8 is equipped with a transverse passage 9 adapted toform a communication between the train pipe 4 and the coupling hose 5.The valve 8 is further provided with a side port 10, opening into thepassage 9 and adapted to establish a communication between the passage 9and the bleed port 7.

The invention includes a standard 11, shown in detail in Fig. 4. At itslower end, the standard 11 is equipped with an enlarged head 12, inwhich is formed a polygonal opening 14 adapted to receive the lug 8 ofthe valve 8. The head 12 is supplied with a depending stop lug'15. Thisstop lug 15 coacts with the stop lug which is usually and commonlyformed upon the casing 6 of the angle cock. At its upper extremity, thestandard 11 terminates in a polygonal end 16. The standard 11 above thehead 12 is of circular cross section and is journaled in a bearing 17which, in the present instance is shown as connected with the forwardface of the end sill 2 of the car.

A lever 18 is provided, the same having an enlarged-head 19 at itsforward end, in which head there is a polygonal opening 20, the contourof which corresponds with the cross section of the end 16 of thestandard 11, the lever 18 being superposed upon the upper end of thestandard 11 and the end 16 of the standard being received within theopening 20. The head 19 of the lever 18 is provided with an outstandingstop lug 21, corresponding to the stop lug 15 of the standard 11 andhaving functions which will be set forth hereinafter. At the rear end ofthe lever 18 is an enlarged head 22, provided with openings 23. Thelever 18 extends transversely of the upper face of theend sill 2 andoperating members 24:, preferably rods, lie above the end sill. Theouter extremities of the operating members 24: terminate in handles 25,located between the ends of the sill 2, the inner or adjacent ends ofthe operating members 24 being pivotally received in the openings 23.Mounted upon the car 1 and in the present instance secured to the upperface of the end sill2 are slide bearings 26 having elongated openings 27through which the operating members 24 pass.

In practical operation, the operating member-s24 may be controlled fromeither side of the car, the operating members actuating the lever 18 andthe lever 18 rotating the standard 11, the standard in its turn,rotating the valve 8 of the angle cock. I At this point it may bestated, that, if desired, the side port 10 in the valve 8 may be broughtinto alinement with the bleed port 7 in the casing 6. In this manner,the train pipe line is cut oil, but the connected cou pling hoses 5between a pair of cars will be permitted to discharge into theatmosphere, through the bleed port 7 and the side port 10.

Referring particularly to Fig. 2 it will be observed that the operatingmechanism is so positioned that it cannot be injured should the draw bar3 be pulled out. The lever 18 and the operating members 2 1 lie abovethe end sill 2, and as a consequence, these elements will be protectedfrom injury and will be accessible and visible at all times.

The end 16 of the standard 11 is of the same cross section as the lug 8of the valve 8, the opening 20 in the lever 18 being of the same size asthe opening 14: in the standard 11. As a consequence, the standard 11may the cock having interengaging elements and the lever and thestandard having interengaging elements, the cock-engaging element of thestandard and the standard-engaging element of the lever being duplicatesto permit an interchangeable mounting of the lever and the standard uponthe cock.

2. In an air-brake system, the combination with the angle-cock of thetrain-pipe line, of a standard mounted on the angle- 1 cock; a levermounted on the standard; and means for operating the lever from a pointto one side of the cook; the standard and the cock having interengagingelements and the lever and the standard having interengaging elements,the coclcengaging element of the standard and the standardengagingelement of the lever being duplicates to per- 1 mit an interchangeablemounting of the lever and the standard upon the cook, the lever and thestandard each being provided with a stop-lug, the lugs respectively, co

acting with the cock when the lever or the standard is assembled withthe cock.

In testimony that I claim the foregoing as my own, I have hereto aliixedmy signature in the presence of two witnesses.

BENJAMIN W. DAVIS.
